Divided and this applicatibnfiled butcher 21, 1926. Serial No. 143,104.

The present invention relates to the refining of hydrocarbon oils, andparticularly to apparatus tor treating such oils with sulphur c acid.The invention will be fully understood from the following description,illustrated by the accompanying drawings, in which Fig. 1 is afragmentary longitudinal section through an elongated mixer {mixingconduit or tube) constructed according to this invention.

Fig. 2 is a transverse section on the line l1ll, Fig. 1; and

Fig. 3 is a diagrammatic side elevation of apparatus, including a mixingtube, for the acid-treating of oil.

Referring to Figs. 1 and 2, reference numeral 1 denotes a conduit withinwhich are arranged a plurality of longitudinally alined pipe or tubesections 2. These sections are sealed at their ends by imperi'orateclosures or caps 23, the caps of the adjacent pipe sec- Oil and acidentering the conduit follow the course indicated by the dotted lines inFig. 1; that is, they are forced by the first of the rings 4 to enterthe first pipe section 2 through the perforations therein, and areforced by the cap 3 at the end of the section to pass out into theannular space surrounding it. A similar arrangement and construction ofthe succeeding pipe-sections causes the mixture of oil and acid totravel in a like manner through them, with the result that the liquidstravel a zigzag path through the mixing tube, flowing into and out ofthe perforated pipe thoroughly intermixed. Y

The mixture of oil and acid passesout of the mixing tube 1 into asettling tank 7 (Fig ure 3), in which a separation of the acid sludgefrom the oil takes place. The sludge,

which settles to the bottom, is drawn ofi through the valved pipe 8. TheOll passes out OI the setting tank through the pipe 9, which conveys mmthe lower portion of a treating tank 10, containing means for secur-,

ing intimate countercurrent contact between the oil' and fresh acidintroduced through pipe 11. The acid sludge collects in the bottom ofthe treating tank, from which it is withdrawn through pipe 12 by pump 13and preferably forwarded through pipe 6 to the top of the mixing tube 1.

"he acid-treated oil leaves the" tank 10 through pipe 14, which conveysit to the settling tank 15. Thence the oil passes through pipe 16 into awash tank 17. Bottom settlings from the tank 17 are drawn oil throughpipe 18. lVash water issupplied to ftank 17 through a pipe 19. From thewash tank the oil passes through pipe 20 to other tanks, not shown, forfurther settling, alkali treating, andthe like, if required.

Various changes and alternative arrangements may be made within thescope of the appended claims, in which it is my intenrations forming thesole means of inlet there-.

to and outlet therefrom, whereby flow through the mixer is continuouslyalternated between the passageway and the tube.

In oil refining apparatus, a mixer comprising an elongated conduit,a plurality of foraminous tubular sections closed at both endslongitudinally. mounted therein and spaced therefrom, partitions fittedwithin the conduit and surrounding the tubular sections, wherebycontinued flow is prevented except through the tubular sections, a tank,a plurality of pipes leading into one end of the conduit for theintroduction of oil and treat- 5 ing liquid thereinto, and a pipe forWithdrawing the mixed liquids from the other end of the conduit to thetank.

In testimony that I claim the foregoing as my invention, I aflix mvsignature.
